问题描述

使用 c#，我从 PE 文件中提取了一个游标资源并删除了 x-y 热点并预先添加了 BITMAPFILEHEADER 但是当我尝试转换为位图以在图片框中显示为 pbResImage.Image = Image.FromStream(bitmapStream.BaseStream); 我收到一个参数异常。

我的代码适用于数十个游标，并且可以使用其他程序提取有问题的游标。

我相信最简单的方法是通过代码 (bitmapBytes) 和 传递给 Image.FromStream (bitmapStream) 的流。我试了又试都没有成功。

我请求您帮助检查输入并确定 bitmapStream 的实际无效内容。一旦我知道 .NET 发现了什么问题，解决方案可能就在手边。

这是我提取的 bitmapBytes 数组：

解决方法

有一种特殊类型的 DIB 图像用于索引光标和图标，其在标题中设置了双倍高度，但实际上在其后面包含一个 1 位 AND 掩码，用于指示哪些像素是透明的。

>

如果你分析标题，你在那里的数据似乎是一个 4 位、32x64 DIB 图像，但它实际上是一个 4 位 32x32 图像的组合，然后是一个 1-位 32x32 掩码。

通过这样考虑，可以准确地检测到这一点；如果高度可被 2 整除，则取高度的一半，然后将给定像素格式下该半高图像的预期尺寸加上每像素 1 位的该半高图像的预期尺寸（请记住，步幅始终是 4 个字节的倍数）。如果这与您获得的图像数据的大小匹配，则您正在处理透明图标格式。

要检查的这个大小值是 biSizeImage 中的 BITMAPINFOHEADER 值，您当前的代码似乎根本没有读取该字段。它是一个 32 位整数，紧跟在压缩类型字段之后。

Boolean isIcon = false;
Int32 maskSize = 0;
Int32 stride = GetClassicStride(biWidth,biBitCount);
Int32 actualHeight = biHeight;
if (biHeight % 2 == 0)
{
    Int32 halfHeight = biHeight / 2;
    Int32 maskStride = GetClassicStride(biWidth,1);
    Int32 maskSizeCheck = maskStride * halfHeight;
    if (biSizeImage = stride * halfHeight + maskSizeCheck)
    {
        isIcon = true;
        actualHeight = halfHeight;
        maskSize = maskSizeCheck;
    }
}

经典步幅公式：

public static Int32 GetClassicStride(Int32 width,Int32 bitsLength)
{
    return (((((bitsLength * width) + 7) / 8) + 3) / 4) * 4;
}

生成的图像：

Resulting image

此格式仅适用于图标文件，不适用于经典位图，这就是为什么您的 bmp 文件头不起作用的原因。因此，要么查看特定的图标/光标文件格式，要么将其转换为 32 位图像并手动将蒙版应用到图像数据上（就像我在生成上面的图像时所做的那样）。

从技术上讲，通过具有 24bpp 基础图像和 8bpp alpha 蒙版，此格式也可用于 32 位图标。在这种情况下，标题中的高度也将加倍。但到目前为止我还没有真正遇到过这种格式。
